1、Principles and characteristics

1、Structure

JG-BSLSeries Intelligent Target Flowmeter mainly by the measuring tube (housing), a new capacitive force sensor (with blocking devices), integrated operator display, and output components. According to different media and conditions, suitable capacitors must be selected force sensor, therefore, provide users with accurate measurement of objects and parameters, the appropriate choice of capacitor manufacturers force sensor can measure accurately the product key. The structure is shown:

2、Works

When the medium flow in the measurement tube, by its own momentum Baffles (target) pressure generated from time to time, and there is a force baffles, the size of its force proportional to the square with the media flow, and its Mathematically expressed as follows：

F=CdAρ·V2/2

Where：F ——Baffles forces suffered（kg）

Cd——Drag coefficient of the object

A ——Baffles axial projected area of the measuring tube(mm2)

ρ ——Medium density condition（kg/m3）

v ——Medium in the average flow rate measuring tube(m/s)

Baffles(Target)Accept the forceF，The rigid connection of the transmission parts (measuring rod) spread capacitive force sensor, capacitive force sensor produces a voltage signal output：

V=KF

Where： V——Capacitive force sensor output voltage（mV）， K——Constant of proportionality， F——Baffles (target) force suffered（kg）

As a result, the voltage signal by the preamplifier、AD Conversion and computer processing, you can obtain the corresponding instantaneous flow and cumulative volume, it works

See diagram：
